How to choose the right metal separator, first understand the classification
A metal separator is an electronic instrument that uses the principle of electromagnetic induction to detect metals and is widely used. There are many metal separators on the market at present. How do we choose a suitable metal separator? For this question, let's first understand the classification of metal separators. The metal separator is divided according to the conveying method of the object to be detected. Usually, the metal separator is divided into: channel type, drop type and pipeline type. Channel-type metal separator The most common metal detection equipment on the market is the channel-type metal separator. The channel of the detector is square. Generally, it is equipped with a conveyor belt mechanism, with an automatic rejection device, or provides an alarm signal. When the items on the conveyor belt pass the detector, once there is metal, it will automatically reject or stop conveying. Mainly for online inspection of finished and semi-finished products, and provide final inspection before shipment. For example: bagged materials, boxed products, etc. Falling metal separators Falling metal separators are generally equipped with automatic rejection devices, so it is customary to call them falling metal separators, or metal separators. The packaging requirements of metal separators for products are that they cannot contain metal, but considering the high requirements of sealing and light-proofing, metal composite films must be used for packaging. The metal composite membrane itself is metal, so if a channel-type metal separator is used, the detection sensitivity will have a large deviation, or even cannot be detected. For the above reasons, testing prior to packaging may be an option. The drop-type metal separator was developed for the above-mentioned situation, and is mainly used for the detection of tablets, capsules and granular (plastic particles, etc.) and powdered items. When these items fall through the falling metal separator, once metal impurities are detected, the system immediately activates the separation mechanism to exclude suspicious items. It has the characteristics of simple installation, high sensitivity, convenient maintenance, high efficiency, stability and reliability. Pipeline metal separators General metal separators cannot completely monitor the entire production process of fluid products, such as ham sausage, chewing gum, oral liquid, etc., and remove metal impurities online in real time to ensure the safe delivery of products to the next process. Under normal circumstances, these products are encapsulated in metal, and they cannot be detected by metal separators after they become finished products. In addition, liquid or viscous items are detected before canning or packaging, which can effectively improve the detection accuracy. The classification of metal separators is briefly introduced here, I hope it will be helpful to everyone. Guangdong Kenwei Technology focuses on the research and development of metal separators. Whether it is the food, pharmaceutical and rubber industries, or the textile, paper, ore and recycling industries, we can provide metal separators and metal detectors that meet their requirements.
